I am building a turbo engine for my car and have a gsr bottom end built golden eagle sleeves je pistons, crower rods and acl bearings, so my question is what head would be the best to use i have a B16 head B17 head and a B18 gsr head what would put out the best numbers?

 

b16 head would be the best choice, but really they all are fine choices, there will be slight compression differences with the PR3 and P72, but this is a boosted application and therefore these slight differences will be negligable. Get the cheapest, cleanest head, and spend the real money on a quality tuner.
